The city of Taguig does not implement the Number Coding Scheme within its internal roads. But the scheme is enforced on the National Roads within its boundaries, i.e. C5, East Service Road and Manuel L. Quezon.

The cities of Parañaque, Marikina, and Muntinlupa do not implement the Number Coding Scheme.

In addition, the following areas in Pasay do not implement the Number Coding Scheme: Ninoy Aquino Ave., MIA Road, Domestic Road, Airport Road, Sales Road, and portions of Buendia.

EDSA, C-5 Road, Diosdado Macapagal Avenue, and Roxas Boulevard are included in the implementation of Window Hours regardless of the city where they belong.

All Public Utility Buses (City and Provincial) are now covered under the Number Coding Scheme, with no “Window Hours”. Motorcycles, on the other hand are exempted from the scheme.
